“…Generally, in the past 15 years alone, more than 25 published research papers have explored connections between dimension and graph theoretic properties of cover graphs and order diagrams (we list some of them: outerplanarity [3,5], planarity [18,13,1,10], cut-vertices structure [22], treewidth [17,9], exclusion of some structures [25,15,6,7], or even more complex structural parameters [11,8]). For our considerations, it is worth mentioning a result in [9].…”
